Technical Specifications

Usage Precautions

1. Circuit Design

• Use within specified rated performance range, avoiding high temperatures, overcurrent, overvoltage, reverse or AC voltage, and rapid charge/discharge circuits.
• Select capacitors with a lifespan comparable to the machine's.
• Ensure complete isolation between capacitor casing, terminals, and circuits.
• Do not use if the capacitor sleeve insulation is insufficient.
• Avoid environments with direct contact with water, saltwater, oil, condensation, or harmful gases (sulfides, etc.).
• Avoid direct sunlight, ozone, UV, or radioactive environments.
• Ensure vibration and shock conditions do not exceed specified limits.
• Ensure proper spacing between capacitor terminals and PCB holes.
• Leave adequate space above the capacitor's safety vent.
• Avoid placing wiring or other components directly above the safety vent.
• Avoid other wiring near the capacitor on the PCB.
• Minimize heat-generating components around the capacitor.
• Consider temperature and frequency variations.
• For double-sided PCBs, avoid excessive substrate holes and vias near the capacitor.
• Ensure current balance for parallel capacitor connections and voltage balance for series connections.

2. Component Installation

• Ensure capacitor terminals do not directly contact each other or short-circuit.
• Verify the installation environment: avoid water/oil contact, condensation, direct sunlight, ozone, UV, or radioactive exposure, harmful gases, and excessive vibration/shock.
• Ensure proper spacing between capacitor terminals and PCB holes.
• Leave adequate space above the safety vent and avoid placing components or wiring there.
• Avoid other wiring on the PCB near the capacitor.
• Minimize heat-generating components around the capacitor.

3. Assembly and Usage

• Prevent direct contact between capacitor terminals.
• Avoid short circuits caused by conductive materials.
• Ensure proper environmental conditions during installation (no water, oil, condensation, harmful gases, direct sunlight, etc.).
• Avoid excessive vibration and shock.

4. Maintenance and Inspection

For industrial use, regular inspections including visual checks and performance tests are required.

5. Emergency Procedures

• In case of safety vent activation during assembly, disconnect the main power or unplug the power cord.
• Keep face away from the vent when activated due to high-temperature gas release. In case of eye contact, rinse immediately with water. Do not ingest electrolyte; if contact with skin occurs, wash with soap.

6. Fumigation Treatment

If exporting products overseas requiring fumigation (e.g., with bromides), be aware of potential corrosion reactions from halide ions. Do not reuse capacitors exposed to fumigant. Ensure thorough drying after fumigation, and consult safety guidelines if unsure.

7. Storage Conditions

• Store indoors at temperatures between 5-30C and humidity below 75%.
• Do not store in environments or conditions prohibited during assembly and use.

8. Disposal

• Dispose of by making a hole or crushing the capacitor and incinerating, or by handing over to a specialized waste recycling service.

9. Environmental Requirements

Products comply with the latest EU ROHS, HF, and REACH environmental requirements. Special customer requirements will be handled as per signed agreements.
